Clap Push-Up

This requires real push-up strength and explosiveness as a prerequisite. If you can't do a clean set of strict push-ups with good form and full depth, don't attempt this yet. Get rock-solid on regular push-ups first. Once ready, do a regular push-up but explode off the ground hard enough that your hands leave the surface completely. Clap once, land softly with bent elbows ready to absorb impact, and go straight into the next rep. Most of the skill is landing safely; bent elbows save you. One bad landing is a face-plant.
